Embodiment Construction

[0020] The present invention will be further described below in conjunction with embodiment, but is not limited to the content on the description.

[0021] Such as figure 1 As shown, according to one aspect of the present invention, a fan blade is disclosed, which includes a hub 1 and several blades 2 uniformly arranged along the circumference of the hub 1, and also includes a centrifugal member 3, which is elastically connected to the outer periphery of the hub 1 Above, when the fan blade rotates, the centrifugal member 3 makes a circular motion with the hub 1, and the radius of the displacement track of the centrifugal member 3 is proportional to the rotational speed of the fan blade. In the present invention, a centrifugal member 3 elastically connected to the hub 1 is provided on the outer circumference of the hub 1. When the fan blade rotates, the centrifugal member 3 rotates with the hub 1 and makes a circular motion around the hub 1. When the fan blade rotates faster ,...

Abstract

The invention discloses a fan blade and a fan. The fan blade comprises a hub and a plurality of blades uniformly distributed along the circumferential direction of the hub and also comprises centrifugal parts, wherein the centrifugal parts are elastically connected with the circumference of the hub; when the fan blade rotates, the centrifugal parts do circumferential movement along with the hub, and the displacement track radius of the centrifugal part is in direct proportion to the rotating speed of the fan blade. The fan blade and the fan disclosed by the invention have the beneficial effects that the centrifugal parts are arranged on the circumference of the hub in a manner of elastic connection, a wind shield of the fan blade can be directly reflected by the size of the displacement track radius of the centrifugal parts, and the visual effect of the wind shield of the fan blade is enhanced, and the wind shield is more intuitive, so that convenience is brought for use of the disabled person with achromatopsia, hypochromatopsia and amblyopia and the like.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a fan blade and a fan. Background technique [0002] At present, the fans sold in the market can only display the fan windshield on the display screen or the remote control, and the old-fashioned electric fans even only display weak LED lights on and off at different positions, and the number or color is different to indicate the windshield. This design is very inconvenient for use, and the visual effect is poor, especially for people with color weakness, color blindness or even amblyopia and high myopia. Contents of the invention [0003] In order to solve the above-mentioned technical problem, the present invention discloses a fan blade and a fan, which solves the problem of poor visual effect of the logo reflecting the windshield of the fan in the prior art. [0004] According to one aspect of the present invention, a fan blade is disclosed, which includes a hub and several bl...
